摘要

各种无机氮是浮游植物的基本营养物质，其含量多寡直接影响着海洋初级生产者的数量。在天然海水中，氮含量一般较低，因而在一定程度上它们常是浮游植物的限制因素之一。渤海水产资源丰富，是我国重要渔场之一，因此对其生原要素的研究实属必要。为配合该水域水产生产农牧化的研究，本文根据多年(1959, 1960, 1983)的资料，通过讨论无机氮含量分布、百分组成及N/P 比值的变化特征，对该水域氮素生物环境作了评价。

Abstract

This research indicates that the trend of the distribution of inorganic nitrogen and N/P in the Bohai Sea are similar to that of the total phytoplankton in most months. The content of inorganic nitrogen in the coastal estuary waters is higher than that in the central region. The increment in ammonia-N content is relative to the activity of zooplankton. In winter, the maximum value of the nitrate-N/P is 7, and the transform of inorganic nitrogen is not sufficient. The content of inorganic nitrogen, which has certain effects on the reproduction of phytoplankton in this area, is lower that that of phosphate.
